8. Assume that you decided to make your own standards that avoid using length. You will still need three basic units, and let's assume you picked time [T], mass [M] and electric charge [C]. Express length [L] using these three "basic” units.

9. A certain quantity, X, can be determined using X = AB – 2C. If A = 20.23 units, B = 11.000 units, and C = 0.095 units, express X with the proper number of significant figures and decimal places. * A. 222.34 B. 222.31 C. 222.3 D. 222 E. 200

I. IDENTIFICATION: Give the name of the physical quantity described by the following units and write F if it is Fundamental quantity or D if it is Derived quantity. Standard unit Name of Quantity Fundamental or Derived 1. Mile 2. Millisecond 3. Hectare 4. m/s 5. Joule 6. Slug 7. Newton 8. Light-year 9. g/cc 10. kilowatt

According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?
